Vimentin is an intermediate filament protein normally expressed in mesenchymal cells, but the evidence of the aberrant expression of vimentin in epithelial cancer cells suggests that the vimentin expression might be related to local invasiveness and metastatic potential. There have been a few previous studies on the vimentin expression in human cervical carcinogenesis using in vivo and in vitro models. We examined the immunohistochemical vimentin expression in various squamous epithelial neoplasms of the uterine cervix, including the cervical intraepithelial neoplasia group (n=25), the microinvasive squamous cell carcinoma group (n=15), the invasive squamous cell carcinoma group (n=15) and the metastatic squamous cell carcinoma group (n=8). Vimentin positivity was significantly higher in the invasive than in the intraepithelial group, and in the cases with lymph node metastasis than in those without metastasis, suggesting a relationship between the vimentin expression and progression of the uterine cervical epithelial tumors.

OBJECTIVES: To know the present conditions of industrial accidents in automobile factories in Korea and make the basic materials essential to prevention of industrial accidents METHODS: We reviewed and analyzed the records of industrial accidents occurred in an automobile factory in 1997 by time of occurrence, job categories(fixed production, skilled trades, mechanical material handling, and clerical 8r technical), type of injury, kind of accident, and location of injury. RESULTS: 1. By age groups, the accident rate was the highest in age 45-49(1.6 %o) followed by age 35-39(1.3 %), 40-44(0.9 %), 30-34(0.9 %), 25-29(0.6 %), and 20-24(0.4 %) and by working duration, it was highest in group of experience over 25 years, and so we could see that the more age or working duration increases the more accident rate increases. 2. By work time, the accident rate was the highest in 10-11 a.m. (21.4 %) followed by 2-3 p.m. (17.9%). By the day of the week, it was as follows, Friday(20.5%) Wednesday (17. 9%), Monday (16. 2 %), Thesday (15. 4 %), Saturday (12. 0 %), Thursday(11.1 %), Sunday(6.8 %) in order. By the month, it was high in May(17.9 %), March(11.1 %), and April(11.1 %) followed by August(10.3 %) and January(9.4 %), so we could see it was high in spring. 3. The most frequent injury was in the back by 41.0 % followed by 17 cases in fingers(14.5 %), legs(9.4 %), hands(7.7 %), head(6.0 %) in order. And by the type of injuries, the sprain was most frequent by 38. 5% followed by fracture(22. 2 %, lumbar HNP(11.1 %), and contusion(9.4 %) in order. The causes of accident were handling heavy materials(34.2 %), upset(17.1 %), stenosis(16.2 %), and falling(6.8 %) in order. CONCLUSIONS: By the above results, to prevent the industrial accidents in automobile factories in Korea, preventive activities for handling heavy materials and back injury, and continuous industrial education are necessary.

Large intestinal Lipohyperplasia (LPH) is a poorly recognized lesion characterized by adipose tissue infiltration in the submucosal layer of the colon. Most of all, LPH developed at Ileoceal valve, especially upper lip which was called by ileocecal valve syndrome. For endoscopists and radiologists, it has often remained difficult to make a distinction from malignant neoplasia. We report here the case of a mild obese, 51-year-old man who had polypoid lipohyperplasia of the colon associated with extreme hyperplasia of the appendix. His chief complaint was recurrent intermittent abdominal pain. The colonoscopic finding was a submucosal tumor-like polypoid mass originating from appendix with smooth surface, But ileocecal valve was intact. Abdominal CT finding was 2.5 cm sized round heterogeneous low density mass like lesion with intratumoral fatty density of cecal tip area with enhancement of peripheral portion. In barium enema study, after retrograde filling of contrast, smooth extrinsic indentation of cecal tip with partial filling of appendix was seen. Histological exemination revealed infiltration of mature adipose tissue in the submucosal layer. Because of recurrent abdominal pain, ileocecal resection was performed at operation. We discuss the case and review the literatures on this subject.

Albinism is an inherited ongenital disarder in which there is sgr neralized decrease or absence of pigrnent in the eyes, skin, and hair. There are two general groups (1) Oculocutneou albinism, (2) Ocular albinism. Skin cancers in albinos are rare in ternperate clirnats and t.hey occur rnostly on sun ex posed areas. We present a case of recurrance of squarnous cell carcinoma ir a Korean albinoid on both sides of the neck and right ear. On liistopathologic examination, we find I or pearls, and irregular mases of epidermal cells that proliferite downward into the devmis. The invaing cell masses are composed of atypical squamous cells.
